Ongoing Activities:

Attitude Training - The FOT continues training on attitude determination,
maneuver planning, and maneuver execution.  The transition date is
tentatively scheduled for 08/18/06.

RIONET - The transition to the RIONET on String 3 will tentatively occur
around mid-September.  

Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the
Library on April 28, 2006.  The delivery to the ACE MOC will not occur until
after the MOC is converted to the RIONET.

Multi-Mission MOC - The FOT has begun supporting the effort to determine the
feasibility of transferring to a multi-mission MOC.

Automation - Development for the next ROBOTT automation release in ongoing
on String 3.  A ROBOTT SPS release is expected no later than September 18.

Anomalies:

DOY 230 (08/18/06)  G06-0077 - ACEDDS unable to change password 
FOT was unable to change the password on the ACEDDS.  The sys admins logged
in and the password was changed from within the root account.
IMPACT:  FOT would not have been able to log in without the help of the sys
admins.  

DOY 231 (08/19/06)  G06-0078 - offline.gen did not run
For unknown reasons, offline.gen did not run after the pass.  The script did
run nominally the next day and moved and archived all history files.   
IMPACT:  Postpass recorder redump list was not created, but fortunately no
redumps were needed.  The pass summary file was not generated.  History
files were not transferred to archive directory until the following day.

DOY 233 (08/21/06)  G06-0079 - Corrupted DSN Schedule
The week 34 schedule file on the DSN Lilypad Server was actually a "Change
Log" for passes that occurred in week 33.  There was no pass information for
the current week in the DSN schedule when ROBOTT went to download it from
DSN.  DR N103859.
IMPACT:  The ROBOTT automation schedule was blank, so ROBOTT would not have
supported the ACE pass without FOT intervention.  

DOY 235 (08/23/06)  G06-0080 - Incorrect CMD MOD Index
The first command was not making it to the spacecraft.  Analysis of the 0158
DSN Monitor Data revealed that DSS-66 had the command mod index incorrectly
set at 0.43 dB vice 1.69 dB.  DR M103823.
IMPACT: The first command had to be retransmitted 10 times before it made it
to the spacecraft.  All commands were received.
